The so-called subviews are usually referred to as auxiliary elements of the system of electrical networks operated at most industrial and domestic facilities. Products of this class are used for secure fixing of electrical accessories in niches in the wall prepared in advance for this purpose. A more detailed acquaintance with the technology of mounting, will allow you to independently install electrical products (sockets, in particular) in your apartment.
Example of installation of a floor plate
Known methods for preparing recesses in the wall designed for mounting plastic podzetnikov, they use the following techniques:
Regardless of the method of installation chosen by you, the arrangement of the arrangement of the seat must begin with the marking of the niche under it.
Marking of places fastenings of sockets (height of their location) should be selected taking into account the requirements of technical standards for electrical safety (ПУЭ), as well as features of the arrangement of furniture in the apartment. The markup itself is reduced, as a rule, to drawing a mark at a selected height and delineating around this point a circle with a corresponding diameter.
Preparation of installation niches in walls made of concrete or brick can be done in one of the following ways:
Crown for drilling a hole
Given that a typical flush mount has a diameter of 67 mm - you should prepare a crown of about 70 mm. After that, using a hammer drill or punch with a crown fixed in the chuck, a corresponding hole should be punched into the wall.
The depth of the hole to be prepared must be sufficient for the plastic case of the product to be completely recessed in the wall (with a margin of about 4 mm).
Accepting a niche by drilling (using a perforator or impact drill) is reduced to punching holes along the marking diameter and to the subsequent shelling of individual fragments of wall material with a chisel.
The use of the grinder markedly reduces the time spent on preparing the niche, but you will also get the most dust on the room. When implementing this method, the marked-up ground is cut by the Bulgarian disk in different directions, after which the wall material is knocked out by a chisel to the calculated depth.
Drilling of the hole for the bottom plate
After niche prepared - make sure that the plastic case of the product is placed in it without any difficulty.
Following this, the electrical cable supplying power to the outlet is inserted into the hole on the back wall, and its case is inserted into the niche as far as it will go.
At the final stage of the installation work, the sub-base to be installed is fixed in the hole with the help of prepared plaster solution. After complete drying of the last case, the finished product case is cleaned of the remnants of gypsum and carefully wiped with a cloth.
Floorboard for drywall
Before how to fasten a podrozetnik on a wall of plasterboard, for example, you should prepare a hole in the material to fit the body of the product being installed, and then fix it using special spacer legs.
When installing in a private country house, a specially prepared plate made of textolite or thick multi-layer plywood is used as a floor plate, the dimensions of which must correspond to the dimensions of the product being installed (slightly exceed them). A similar method of installation is used, as a rule, when open wiring in buildings, the walls of which are made of timber or other wood materials.
